how to get two max values

Currently Being Moderated

Hi experts

I am stuck with the problem .looks easy but i unable to solve it .

Using BoXi 3.1 webi Olap cubes.

here my data looks like this

country   city  sales revenue

aaa       xxx     100

aaa       yyy     200

aaa      zzz     300

bbb       ddd    100

bbb       sss    200

bbb       ppp     200

ccc      qqq    300

what i would like to see my table is like

country    sales revenue

aaa         500

bbb         400

ccc         300

i want the first max and second max  from country aaa and sum it up. In the same way for the country bbb here lies the problem if both the values are max then i would like to aggregate both the values and have to show it as 400 .

Much appreciated with inputs.

Thanks and regards

sunil

Hello,

Use the Rank function  to get the top Sales revenue per Country.

Create a variable to sum the sales revenue with rank 1 and 2 for each country.

If the rank is same then take the average or only one value.

In you example for country bbb the average for 200 and 200 will be 200, so the sum will be 200+300=500 and not 400.

Thanks,

Vinay

Hi Sunil,

You can try the following also

The main report looks like

Now apply break on state and part of report looks like

Apply ranking on city based on sales revenue with top 2

Now the report looks like

Now apply sum on the sales revenue

Hope this is what you are lookinf for.

Hi

First of all thanks  for ur  reply, I think u didnt properly understood . i want to show the data only on country.with the sum of two max values. when we use rank then we will get max value.but what if the values are same can u aggregate it ?? i am thinking abt the solution for that !!!

Even if the values are same, if they are max values, then they will be shown after applying the ranking. And the aggregated value will be shown by sum function as well.

Thne you can suppress the city column. The rpeort looks like this before suppressing the city column. Note that the state Illinois has same values for Chicago and Minneapolis and they are aggregated.

Now you suppress the city column to get your desired result like this

IT can be even better formatted by removing the break header and break footer and addming table header

Hi sunil,

I took ur example data and produced the output you want.

Gothrough the screen shot.

Create one variable called rank

Place that in Table.

right click the rank column and filter the values for 1 and 2.

now remove the city column

Now as expected  output  has came.

If you want to hide the rank ,do colouring white and hide the rank
